Mom kills baby daughter: Mother of nine deliberately smothers newborn

Mom kills baby daughter: Mother of nine deliberately smothers newborn, Sad news out of Arizona comes on Sunday, April 28, 2013, as a 36-year-old mother of nine children has been arrested for allegedly killing her own newborn daughter. The Inquisitr reports that Nina Koistinen is accused of deliberately smothering her six-day old daughter, and ninth child overall, named Maya.

Local police state that Koistinen intentionally smothered Maya back on April 8, 2013. She did it by covering the child's mouth and pinching her nose so that she could no longer breathe. Word is that the mother was overwhelmed with the number of children she had, but she was also jealous of the attention the child was receiving from her husband, Bradley.

Nina Koistinen told her husband that she had accidentally fallen asleep on top of the baby while feeding her.

After Bradley found the baby unresponsive, the child was quickly taken to Paradise Valley Hospital and pronounced dead about 45 minutes later. An autopsy showed intentional signs of suffocation.

With that being said, the police checked into the family's history and found CPS reports with unsettling news. Prior reports had comments documented from Nina saying she had wanted to suffocate her other children or wished they would die in a car crash.

Shortly after this discovery, Nina confessed to police through her husband that she had smothered little Maya. She even revealed exactly how she did the horrible act.

In Nina Koistinen's first court appearance on Friday, her husband pleaded with the court claiming they were working on controlling his wife's mental illnesses. Bradley Koistinen said his wife battled schizophrenia, depression, and bipolar disorder.
